MOSCOW, January 23. /TASS/. Experimental design work (OKR) to create a radar system for the fighter fifth generation T-50 (PAK FA) is almost complete, has created the first production models. In an interview with TASS said the General Director of Scientific research Institute of instrument design (NIIP). Tikhomirov (included in the Group of ASD "Almaz-Antey") White jury.

"The corresponding R & d is at the final stage. Moreover, the head, produced by the Ryazan State instrument plant - already made the first production models of AESA (active phased array antenna - approx. TASS)," he said.According to White, flight tests of a new radar "go without any comment". "But how long they will last, to tell now difficult in many respects, it does not depend on us," said White.PAK FA - promising fighter fifth generation. He made the first flight in 2010. As expected, the first five production aircraft will go to the troops in 2017.

While this videos is really concerning in-flight refueling, it features T-50 prominently, it appears the all-grey aircraft is the T-50KNS, right? I am puzzled by the star markings on the nose though, as this is as far as it's known a ground tetsts airframe which never flew.

This one line quote show how sometime of better frequently text translated from russian to english are so obscure and ...In this case it quit clear that main means definitive version but on a text of tents of lines you get to lost yourself in translation...

Flight testing starting in 2017. So they have basically completed the design and component engineering. It is all about refinement and debuggingfor the next 3 years. Does not look like they are in a super hurry to deliver the product, which is very wise. A lot of internet "experts" have time frame gut feelings detached from reality. Ten years for design and testing is very reasonable for such a device.

The English in this article is very sloppy. They talk about R&D completing by 2020 at the same time that they talk about flight testing. Thisis not the correct used of the term R&D.

I suspect the success of body lift with the Flanker and Fulcrum series.

The widely spaced engines means more space for weapon bays but also with regard to thrust vector control engines the wide separation means much better differential control... ie with the engines together pointing one nozzle up and one down will create a tiny roll force.

Separating them by a metre or more means much more powerful roll control forces with smaller angle deflections needed.
